I started my 46 gal tank yesterday, filled with salt water and live sand. As of right now Im using a biowheel penguin 200 (getting a SKIMMER later), And bought a Penguin 550 Powerhead, I was thinking about buying a HYDOR KORALIA 4 1200GPH as well. Would that be too much?? should I may be go with a KORALIA 3 instead?? Im thinking about having corals in the future, so I want something wich is going to allow me to have different kinds of LPS, Mushrooms, SPS, etc..
